Adaptive optics in astronomy.
Abstract
After a brief discussion of how the earth atmosphere modifies stellar images, the paper reviews several adaptive optics techniques for obtaining diffraction-limited information. Consideration is given to the use of 'rubber mirrors' which are mirrors that are distorted in real time in such a way as to at least partially compensate for aberrations introduced by the earth atmosphere. Corrected-FOV and signal-to-noise considerations are discussed.
